基于小波分析的数字水印算法研究摘要本文通过对数字水印算法的研究和讨论，实现了基于空间域及变换域的数字水印算法，并进行了相应的鲁棒性测试。论文首先介绍了数字水印的基本特征、原理以及目前国内外的研究现状等基本问题，给出了数字水印的理论模型，并根据数字水印的不同特性进行了分类，为水印算法的提出、实现及测试提供了理论依据-Wavelet-based Digital Watermarking Algorithm Abstract Digital Watermarking Algorithm Based on the research and discussion, and implementation based on the spatial domain and transform domain digital watermarking algorithm and the robustness of the corresponding test. Thesis first introduced the basic characteristics of digital watermarking, theory and research at home and abroad such basic questions, give a theoretical model of digital watermarking, digital watermarking based on the different characteristics of the classification, for the proposed watermarking algorithm, implementation and test provides a theoretical basis
